Busbar fork connector 3P 100A 16 mm² 12 modules - Eti-Polam IZ16/3F/12

Eti-Polam IZ16/3F/12 is a three-pole fork-type busbar connector rated for 100 A and intended for use with conductors up to 16 mm². Designed to occupy 12 DIN-modules, this busbar fork connector provides a compact way to link phases, distribute power and create secure connections between circuit breakers and other DIN-rail mounted devices in residential and commercial distribution panels.

Advantages

The fork design ensures a reliable mechanical and electrical contact with terminal screws while simplifying installation and removal. Its 100 A current rating and compatibility with 16 mm² conductors support common wiring standards for small and medium distribution circuits. The 12-module footprint allows organized mounting on standard DIN rails, reducing panel clutter and enabling neat phase bridging and distribution.

Suitable for

• Connecting and bridging phases between DIN-rail circuit breakers and modular devices
• Power distribution in residential electrical panels and small commercial switchboards
• Quick installations where a fork-style busbar provides faster assembly and reliable contact

When it may not be suitable

This connector is rated for 100 A and for conductors up to 16 mm²; it is not suitable for higher-current installations or for cables with larger cross-sections. It is intended for use in standard modular distribution systems and may not fit non-standard or proprietary mounting systems, specialty enclosures, or situations requiring fully insulated busbars with different geometry.

Key specifications

• Poles: 3 (three-pole)
• Rated current: 100 A
• Conductor cross-section: up to 16 mm²
• Module width: occupies 12 DIN-modules
• Type: fork / spade (widełkowy) busbar connector for modular rail mounting

How to use

Mount the connector onto the DIN rail in the desired position, aligning it with the terminals of the devices to be bridged. Insert the prepared conductor (stripped to the appropriate length) into the fork terminal and tighten the terminal screw to the manufacturer-recommended torque to ensure a secure electrical and mechanical connection. Verify that the connector is properly seated on the rail and that all connections are tight before energizing the circuit. Follow local electrical codes and safety procedures during installation.

What to consider before purchase

• Confirm the required current rating and conductor cross-section for your circuit (100 A, up to 16 mm²)
• Ensure the 12-module width fits available space on your DIN rail or inside the distribution enclosure
• Check compatibility with the terminal screw size and type of devices you plan to bridge

Usage recommendations

Use the connector only with properly sized conductors and tightened to recommended torque values; inspect connections periodically for signs of looseness or corrosion. For higher currents or different conductor sizes, select an appropriately rated busbar connector or consult a qualified electrician.
